Abstract
Wireless Sensor Network (WSN), is in the rapid development and widely applied to many fields in recent years due to its low cost, low power consumption and so on. This thesis focuses on the design method of low power consumption and small size WSN node based on ZIGBEE protocol. The main research work and achievements of the thesis are as follows: Firstly, WSN ZIGBEE protocol is researched in detail. The architecture and each layer's function of ZIGBEE protocol are analyzed, and a node design method based on ZIGBEE protocol is proposed. Secondly, design methods of WSN node are discussed. CC2420 RF chip and ATmega128L microprocessor are chosen as the main chips, and their features and performance are described in detail. Furthermore, design methods of each module circuit are introduced.
